          The Acl package contains utilities to administer Access Control
          Lists, which are used to define more fine-grained discretionary
          access rights for files and directories.

        <p>
          Modify the documentation directory so that it is a versioned
          directory:
        </p>
        <pre class="userinput">
<kbd class=
"command">sed -i -e 's|/@pkg_name@|&amp;-@pkg_version@|' include/builddefs.in</kbd>
</pre>
        <p>
          Fix some broken tests:

        <pre class="userinput">
<kbd class=
"command">sed -i "s:| sed.*::g" test/{sbits-restore,cp,misc}.test</kbd>
</pre>
        <p>
          Additionally, fix a bug that causes <span class=
          "command"><strong>getfacl -e</strong></span> to segfault on overly
          long group name:
        </p>
        <pre class="userinput">
<kbd class=

    libacl/__acl_to_any_text.c</kbd>
</pre>
        <p>
          Prepare Acl for compilation:
        </p>
        <pre class="userinput">
<kbd class="command">./configure --prefix=/usr    \
            --disable-static \
            --libexecdir=/usr/lib</kbd>
</pre>
        <p>
          Compile the package:
        </p>
        <pre class="userinput">
<kbd class="command">make</kbd>
</pre>
        <p>
          The Acl tests need to be run on a filesystem that supports access
          controls after <span class="application">Coreutils</span> has been
          built with the Acl libraries. If desired, return to this package
          and run <span class="command"><strong>make -j1
          tests</strong></span> after <span class=
          "application">Coreutils</span> has been built later in this
          chapter.
        </p>
        <p>
          Install the package:
        </p>
        <pre class="userinput">
<kbd class="command">make install install-dev install-lib
chmod -v 755 /usr/lib/libacl.so</kbd>
</pre>
        <p>
          The shared library needs to be moved to <code class=
          "filename">/lib</code>, and as a result the <code class=
          "filename">.so</code> file in <code class=
          "filename">/usr/lib</code> will need to be recreated:
        </p>
        <pre class="userinput">
